ICE-HARVESTING MACHINE.

To all whom it may concern:

Be it known that I, EUGENE LAKE, citizen of the United States, residingat Cooperstown, in the county of Otsego and State of New York, haveinvented certain new and useful Improvements in Ice-I'Iarvesting lIachines, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to ice harvesting machines and has for itsprimary object to provide improved means for mounting and quicklyadjusting the saw-carrying shaft.

Another and more specific object of the invention resides in theprovision of a body including parallel longitudinal runners, a guideframe mounted upon said body at its forward end, a saw shaft supportvertically movable in the guide f'aine, means carried by said supportand engaged with means upon the frame to prevent transverse moveandguide whereby the gage blade may be. easlly and quickly ad usted, andmeans for holdlng the gage 1n 1ts operative or moperative position.

A still further ob ect of the lnvention is to generally improve andsimplify the construction of machines of the above cl1aracter, to reducetheir manufacturing cost, and to provide a machine of great durabilityand high efliciency in practical use.

With the above and other objects in view as will become apparent as thedescription proceeds, the invention consists in certain constructions,combinations and arrange ments of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which Figure 1 is aside elevation of an ice harvesting inachineembodying the presentinvention. Fig. 2 is a top plan view thereof; Fig. 3 is a section takenon the line 3--3 of Fig. 1; Fig. f is a section taken on the line 4: lof Fig. 1; Fig. 5 is a section taken on the line 55 of Fig. 2; and Fig.6 is a dc tail fragmentary plan view illustrating a slightly modifiedconstruction of the gage.

ignates the parallel longitudinal skids or runners which are providedupon their lower edges with the metal shoes 6.

7 designates the central longitudinal runner, said runner and the siderunners 5 being connected by a plurality of transverse rods 8. Anobliquely disposed brace bar 9 connec. s adjacent transverse bars 8 andprov des a support for the centrally located ongine .10 which providesthe power for the operation of the saw blade-carrying shaft.

Adjacent the forward end of the machine body, spaced uprights 11 aresuitably secured at their lower ends to each of the runners 5 and 7, andthe outer pairs of uprights are braced by the inclined bars 12. At theirupper ends, the uprights 11 are connected by the parallel transversebars 13. These several pairs of uprights constitute a guide frame forthe shaft carrying beam ll which is movable in a vertical plane betweensaid uprights. This beam carries the spaced bearing standards 15, saidstandards being disposed between the uprights of each pair and providedupon their lower ends with the removable cap plates 16 whereby the sawblade-carrying shaft 17 may be readily mounted upon the lower ends ofthe bearing standards or removed therefrom. Each of these standards atits lower end and upon one side has integrally formed therewith, spacedcars 18 between which a peripherally grooved roller 19 is mounted. Uponthe opposite side of the bearing standard, the same is provided with avertical groove or recess 20. In the opposed edges of the up rights ofthe guide frame, metal strips 21 are secured. These strips which arearranged on the rear uprights are engaged by the grooved rollers 19mounted upon the lower ends of the standards while the other metalstrips 21 on the forward uprights are received in the grooves orrecesses 20 of the bearing standards. It will thus be apparent that theshaft carrying beam and the bearing standards are held in the guideframe against transverse movement. The saw blade shaft is provided witha sprocket indicated at 22 which connected by an endless drive chain 23with a similarsprocket upon the engine shaft. In the operation of themachine, there is a rearward pull upon the saw blade shaft, and it isfor this reason that the anti-friction rollers 19 are mounted upon therear sides of the bearing standards. Thus friction is reduced to a anadjusting screw which that by simply turning the adjusting screw,

the saw shaft carrying beam may be raised or lowered to position the sawblades inclicated at 2? with. relation to the surface of the ice field.

Upon each of the side runners 5 adjacent to the front and rear endsthereof, a gage is mounted to insure a cut of the desired width by thesaw blades. This gage consists of a plate 28 and a second relativelynarrow plate 29 which is disposed adjacent to the runner 5 and in spacedparallel relation to the plate 28. These plates are connected at theirends by the tubular rods 30, said rods being provided upon opposite endswith exterior screw threads to receive the nuts 31 which have clampingengage-- ment with the plates 28 and 29. The outermost plate 28 isadapted for engagement and movement in a groove previously cut in theice field by the saw and guides the movement of the machine so that ablock of predetermined width will be cut. The lower edge of the innerblade 29 rests upon the surface of the ice and limits the downwardmovement of th plate 28. An obliquely disposed yieldable bracing plate32 is ar ranged between the plates 28 and 29 and secured to the same atits ends. The nuts 31 may be adjusted upon the ends of the tubular rodsto position the outermost plate 28 with relation to the runner 5 so thatthe width of the ice blocks out by the saw blades may be varied whendesired.

33 designates spaced rods which are pivotally mounted at one of theirends as indicated at 3 1 upon the runner Each of these rods is providedwith a series of spaced openings which are adapted to register with thespaced openings 36 provided in the tubular rods 30 within which the rods33 are disposed. inserted through these coinciding openings to securethe rods and 30 together. It will thus be seen that a general adjustmentof the gage plate with relation to the runner may be easily and quicklyobtained by simply sliding the tubular rods upon the rods A rod 38 ispivotally connected at one of its ends to the gage plate 28 and isprovided adjacent its other end with a plurality of rack teeth 39. Theseteeth are adapted to engage with the edge of a plate 40 mounted upon oneof the inclined braces 12 of the uprights 11 of the guide frame for thesaw plate 25 cent-rally fixed to Pins 37 are adapted to be.

shaft. Standards or supports 41 are also provided upon the rear ends ofthe runners upon which similar plates are arranged for engagement by therods 38 connected to the rear gage devices. The plates to are bent uponthemselves to provide resilient end portions 12 adapted for engagementwith the rods38 to hold the ratchet teeth thereof in engagement with theedges of the plates 40. It will thus be seen, that the gage plate may beraised or lowered and held in its operative or inoperative position bysimply adjusting the notched or toothed portion of the rod 38 upon theplate 40.

In Fig. 6 of the drawings, I have illustrated a. slightly modified formof the gage, wherein the same consists of the plate 28 arranged upon theouter side of the bar 43.

The plate and bar are provided with coin- Y 4 ciding openings to receivethe outer threaded ends of the rods 4 1 which are pivotally mounted attheir inner ends upon the runners 5. Clamping nuts 45 'are threaded uponthese rods to adjust the plate and bar a longitudinally upon the rodsand securely clamp the same in their adjusted positions. A bracing bar4-6 is loosely connected at one of its ends to an eye 47 fixed to therunner and is provided with a plurality of open ings 48 in its other endto receive the upper end of a threaded bolt 49 mounted in the bar 41-3.A. nut 50 is threaded upon the upper end of this bolt whereby thebracing bar is adjustably secured to the gage and tudinal adjustmentthereon.

From the foregoing, it is believed that the construction and manner ofoperation of my improved ice harvesting machine will be clearly andfully understood. As the device comprises but few elements which are allof simple form, it will be obvious that the same can be manufactured atsmall cost. Themachine is also highly durable in its construction andefiicient and reliable in practical operation.

While 1 have shown and described the preferred construction andarrangement of theseveral parts, it will be obvious that the inventionis susceptible of considerable modification therein without from theessential features or sacrificing any of the advantages thereof.

Having thus described. the invention, what is claimed is:
